Technical Specifications Category Specification Model R622H-DGJ Type High-Performance Rotary Control Valve (Eccentric Plug) Body Style Flanged, Angle Pattern (Standard for R/ET series) End Connections Flanged, ANSI Class 300 RF (Interpreted from "62-2") Valve Size Likely 2-inch (DN50). The exact size is defined by the "62" code. Trim Characterization Eccentric Rotary Plug with approximately equal percentage flow characteristic. Trim Material & Type Hardened Stainless Steel (17-4PH) for erosion/cavitation resistance (Interpreted from "H"). Leakage Class With metal seats, typically ANSI Class IV (0.01% of rated capacity). Tight shut-off (Class VI) may be achievable with special seats. Actuator Type Pneumatic Spring-Diaphragm Actuator (defined by "DGJ" suffix). Actuator Action Determined by "DGJ" code. Could be direct-acting (air-to-open) or reverse-acting (air-to-close). This must be confirmed from the datasheet. Air Signal Standard 3-15 psig (0.2-1.0 bar). Spring Range Defined by the "DGJ" code (e.g., 3-15 psig, 6-30 psig, etc.). Temperature Range Standard from -50°F to +450°F (-46°C to +232°C). Extended ranges possible with special seals.
